> 1. did XSM hooks are placed in the source code of xen manually?
Yes.
> 2. how to identify security-critical operation?
This is why the answer to 1 is yes. It requires reasoning about what different
security policies might want to enforce, what might be exploitable or could lead
to convert channels, etc.
> 3. does the XSM hooks cover all the operations completely?
Probably not. Certainly not with new features, anyway.
